That is not true.

If it were true, then film cameras wouldn't routinely have flash sync speed limitations in the 1/160 to 1/250 range - but they do.

Yes, their "rolling"/traveling-slit shutter moves MUCH faster, but it still exists.  You can see this, for example, when shooting a Philips Hue bulb at high mechanical shutter speeds - the 600Hz PWM frequency of RGB Hue units (at least older ones from a few years ago, newer ones might PWM faster???)  means that even fairly fast shutters can still exhibit noticeable banding.
